In the drawin ,1 have illustrated my in"-,

heads or ends 4 of the completedfvessel- 5 are to be set somewhat flaring.

The first operation tobe performed uponfl v r p x nei' end of the slide or holder 26 and the 'adjacent port-ion of the lever'27, which is prefan angle to form the edge. f0lds,6 .t hereon, and which at a subsequent operation are turned or pressed flat againstthe upright;

walls 7 to provide the vessel 5.with a'sn'i'ooth mouth Sat its upper side edges. The ends 4 are of U shape corresponding to the cross sectional form of the body, an are provided each with a right angle seam-flange 9, which is to be'interfolded with the projecting end or flange 10 of the body to form the lock or double seam 11 which unites the body to the head or end, the end fitting inside the U shaped body. Each of the eads 4 is provided at its upper horizontal edge with a right angle flange 12, preferably wider than the seam flange 9, and which is to be curled or formed into a false wire 13 at the upper or mouth end of the finished vessel. v

14 is the frame of the machine, 1:) a feed table or guide alon which the Hat body blanks 1 are moved by the blank feeder 16, first to the edge folders 17, 18,:md then to the stationary clamp bar or support 219, below one of the U sha ed body former horns or anvils 20 on the intermittently rotating carrier or turret 21, and body ormers 22 which bend or form the flat blank upward into U shape around the body former horn.

The blank feeder 16 preferably consists of a pair of reciprocating bars furnished with two sets of feed awls 220,'one set advancing the body blan 1 to the edge folders and the other set advancing the edge folded blank to the bod former horn and body formers. Each-o the forward pawls .220 is furnished with a spring 23.

The edge folders for forming the hook or edge fold 6 at each straight side edge of the' blank preferably comprise a stationary folder or member'l? having a forming or shapingedge 19,,and a movable edge folder 18 having a projecting lip orblade '24 with folder having a downward and inward movement "about or in respect to the stationary edge folder.-

wardmovementsfit is mounted on of secured to a slide or holderlfi which reciprocates upon and-is carried by a lever or vibrating arm '27, pivoted to the frame by-e pin 28, and with which the holder or slide 26 is connected'by toggle links or arms 29, 30, so that the operating linkBl which is connected to the tpggles 29, v30, may serve to both operate or vibrate the lever 2Tand, re

c'iprocate the slide or holder 26 thereon, and therebydimpart to the movable edge folder 1'8,"firs t-a downward movement to turn a. right anglevfold on .theblank and then an inward movementto .t'lirn such right: ang le fold inward-intothe' shape shown in F 15. Springs-32 are interposed between the in-' crably 'of'ayoke or rectangular form. The

an inclined upper face 25, the movable edge T0 impart of the movable edge folders 18 its downward and insprings 3-2' hold :the slides or holders 26 in their .outwardposition, as shown in Fig. 7.

until after the lever :27 has been sufliciently depressed'to ca'rry theedge of the folder lip 24'belo\v the shaping ed e 19 of the stationary edge folder 1 7, and then the further downwardfmovement of the operating link 31, actin' upon the toggles .29, 30, causes the edge fol er slide or holder 26 to move inward and this complete the formation of the hook or edge fold 6 on the side edge of the blank. Although the springs 32 are ordinarily sufficient to keep the slide '26 in its outward position until the movable edge folder is carried sufliciently below .the stationary edge folder. I prefer to provide the movableedge folder or its slide"with a guard or safety pin or device 33, which by engagement with a stationary block or esca'pcmcnt 34 on'th'e frame of the machine serves to positively prevent the edge folder slide 26 from being moved inward by the toggle arms 29, 30 until after the movable edge folder 18 is properly depressed below the'stationary edgefolder 17.

To hold the body blank 1 flat and properly clamped against the stationary edge folders 17, 17, during-the edge folding operation. the edge folder operating levers 27 are each furnishedwith a clamp 35, backed up bysptmgs36, surroundingl the guide pins 37.of

the clamps or blank olders 37. And to further and in holding the body blank l'in a-straight flat form during the ed e folding operation, I preferably provide flat spring clamps or guides 38 above the stationary "feed table or guide 15. The spring clamps serves to clamp the blank at its middle poror guides 38 are secured to rods or arms 39 attached to the stationary frame of the machine. v

Each of the body former horns or anvils :20 on the turret or carrier '21 conforms in cross section to .the U shape of the vessel 5 to be produced, and is somewhat shorter in length than the body portion '1 of the vessel, so that the end portions of the U shaped body 2 will-project (sutliciently to receive the heads or ends 4) beyond the end faces 40 of the horn. which are preferably of bardened steel for cooperation with the seam forming and seam closing dies. The horns or anvtls 20, which are preferably fottr in number. are preferably reinovably secured to the turret or carrier 21, which is preferably in the shape of a four-armed spider rotating about a vertical axis. .Each of the horns '20 is also provided at its bottom portion with a recess -11 to receive a movable spring-backed clainp or member 42 which tion against the stationary clamp or b a'nk support 19 on the frame of the machine when the edge folded blank is first fed or advanced under theliorn or anvil 20 by the feeder It. This clampbar or member 42 also serves the further function of ejecting the finished vessel 5 from the born 20 at a subsequent or final stage of the operation. The movable clamp bar 42 is supported by guide pins or screws 43, the heads of which tit in countersunk reces es in the clamp'bar. The springs 44 which are interposed be tween the clamp bar 42 and the born 20 are preferably three in number.

The body formers 22 are preferably in the form of rollers and are mounted on the body former levers 45 which are fulcrurned on the rock shafts 46 on the vertically movable slide .47, which re'eiprocates on suitable guides or u night rods 48 on the stationary frame of tte machine. Springs 49 interposed between the lower ends of the levers 45 and lugs 50 on theslide {T serve to press the body former rollers 22 together or to-. ward each pther and ('ttlbt' them to hug the body former born 90 as they bend and carry the blank upward and around the born :20.

The clamping dies 51. one pair for each body former horn. and which scrvt 'to clamp and hold the shaped body '2 on and again t the born after it has been formed thereon and wlnch are furnished with an operatmg link or member .76 which is engagedby an v arm ffion the rock shaft ltrwhen the slide or cross head 47 makes its up stroke to cause the body formers 2'2 to bend or fornrthe blank around the born 20. The rocksliafts 46 are furnished with further arms 58, which are engaged by a supplemental cam 59 to impart to the link 56 aslight; further movement after the upward movement of the slide 4i is completed. this slight further movement of the link-16 carrying the toggle arms 5-1, 55 past the center and thus locking the clam )ing dies 51 in their closed posir tion, and thereby retainingfthe U'shaped body 2 0n the horn during the subsequent o rations of the seam forming and scam c osing dies,' into registry with which the bod is brought by the step by step rotary movement of the turret or carrier 21.

After the vessel 5 has been completed by seaming the heads or ends 4 toj the body '2, the operating links or members 56 of1 the pairs of toggles 54, 55 are moved to unlock the toggle and retract the clamp dies 51;by means of bent levers 60, connected together by a link 61, and one of which is engaged by a stationary cantor member 62 onHthesta tionary frame of the machine as the carrier rotates. m):

The heads or ends 4. with the flanges 9 and 12 already formed thereon feed downthe stationary head feed chutes 63 on the frame of the machine into theshort supple mental chutes 64 on thecarrier, one 'at each end of each of the horns-20 and through these supplemental chutes into the 'pro'ecting ends 10 of'the U shaped vessel bot y 2. Each of the feed chutes 63 is provided with an escapement, trigger, or head feederttfi. adapted to engage the wider, flange 1'). of the two lowermost: heads 4 and thus support the heads 4, in the chute 63 until llllSlIttttl feeder or escapcment is operated orreleased. The escapementor feeder 65 is preferablyin theform of a leverand is preferably tip erated by a cantor projection 66 onv the short chutes 64 on the carrier. The levers 63 are returned to their normal positionby springs 1G5. p The scanrforming dies 67, one .for each end of the 'U shaped body 2. are each preferably furnished with a vel lip or mouth US to insure the entrance of the projecting end or tlange 10 of the U shaped body 2 within the seam forming groove 69 of the die 67 as the die-advances. Each of the seam forming dies (-7 is also provided at its upper edge with a straight. horizontal curl ing or wiring die-groove In which operates to curl the projecting wide llangc 12 at the upper edge of the head 4 into a roll or false wire 13. as will be readily antlers-total from Fig. 18 of the drawing. The seam forming dies 6? are preferably secured to horizontally reciprocating slides or holders 71 which move back :1nd forth in suitable guides 72 on the frame of the machine and are preferably operatcd as required by bent.

levers 73, the inner arms 74 of which are en inner arms 74 of whichengage an operating,

'block or member 75.

Motion may be imparted to the several movable" or operating devices of my inn-- proved machineby any suitable operating or connecting mechanism. In practice, however,-I'prefer to impart the required intermittent or step by step movement to the rotary-turret or carrier 21 front the main driving shaft 78, having fast and loose pulleys 79, 80, through a worm 81 thereon, which engages a'worm gcarSl on the upright shaft 83, which tits within the stationary column 84 of the frame and which has near its lower end a spur gear 85, meshing with a spur gear 86011 the upright shaft 87, which carries at its upper end a member 88 of a Geneva stop movement, the other member 89 of which is on the hollow shaft of the turret or carrier 21.

The blank feeder 16' is preferablv reciprocatedas re uired through a have gear 90 on the uprig t shaft 83, which meshes with a bevelgear 91 on the countershaft 92, having a gear92 meshing with bevel gear 92' on shaft 92 which is furnished with a cam 93 enga connect'iad by iinfi V rock shag-97 having an arm 98 which is a. roller 94 on, a lever 95 95 to a. crank arm 96 on connected by a link 99 with the 'feeder 16. The edge-folder operating links or members 31 are preferably actuated, as required,- from the upright shaft 83 through the bevel ars 90, 91, 92 which latter mrshcs with a evel ear 100 on the (Olllll(1' lltlfl 101, which has a sprocket wheel Hi2 connected by a chain 103 with a sprocket wheel 104 on the cam shaft 105, which is furnished with cams 106' engaging rollers 107 on the slides 108 which are connected with the operating links or members 31 of the edge folders, and which reci rocate vertically in suitable guides 109 on tiie frame offthe machine.

The body formers 22 which fold the blank upward about the born 20 and their slide 47 and the parts connected therewith are preferably operated as required by .a earn 110 on the cam shaft: 92, which engages an antifriction roller on the slide 47, and which .cam is preferably formed integral with the cam 59. 1 The seam forming dies 67 and seam closing dies 76, and their operating blocks 75, arepreferably actuated at'intervals as required by ashaft 112, having crank arms or eccentric wrist pins 113 at each end thereof as will be evident from an inspection of Figs. 1 and 3,; which are connected by links 111 with the operatixig blocks 75, and which shaftisadapted to be clutched at; intervals with the continuously belt driven fly wheel 115 by a suitable clutch mechanism 116, 117,

The clutch collar-116 is fast on the shaft 119. and itcarries a sliding clutch pin 117 backed up by a spring 121. The clutch pin is retracted and released by a movable segment cam 118, the stem of which slides up and down in the bracket. 122, and which is retracted to permit the clutch pin to connect the clutch collar with the fly wheel by a lever 119, which is oaeratcd by a cam 120 on the gear 85 carrier by the upright shaft 83. spring 123 holds the segment cam 118 in its normal or unclutchcd position.
